Application filed February 10,1898. Serial No. 669,870. (No model.)

T0 all whom, it may concern: I

Be it known that I,'JOHN S. GOLDBERG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a ne'w and useful Automatic Machine for Feeding, Inserting, and Setting Lace-Fasteners, of which the following is a specication.

This invention relates to automatic machines for feeding, inserting, and settinglacefasteners.

The object of the invention is to provide a machine of simple construction and efficient in operation for automatically distributing, feeding, inserting, and setting lace-fasteners, and it is particularly designed for use in feeding, inserting, type, form, and construction set forth in PatentNo. 586,818, granted July 20, 1897, to E. D. Heinemann.

The invention consists, substantially, in the construction, combination, location, and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally specitically pointed out in the appended claims.

Referring to the accompanying drawings and to the various views Aand reference-signs.

The same part is designated by the same reference-sign wherever it occurs throughout the several views.

In a com panion application executed jointly by myself and E. D. Heinemann, Serial No. 670,567, filed February 16, 1898, is shown and described an automatic machine for inserting and setting lace-fasteners and wherein certain features, combinations, and arrangements of elements constituting our joint invention are claimed and wherein, although claim is made only to certain features and combinations as our joint invention, the entire machine is described specitically and in detail in order to enable a complete understanding of the construction, arrangement, and coperative relation of the apparatus. In the present application the same construction in all its IOO details is shown in the drawings, but only such parts and combinations of elements as form the subject of my sole invention will be claimed herein.

In the drawings reference-sign A designates a suitable framework of a construction and arrangement adapting it to support the several parts of the apparatus. In the fram ework is suitably journaled to rotate a main driving-shaft B, upon which may be mounted suitable driviiig-gears-such, for instance, as fast and loose pulleys C D-adapted to receive rotation from any suitable or convenient source and through whiclrmotion is imparted to the various operative parts of the apparatus.

In the particular form of apparatus shown, to which, however, I do not desire to be limited or restricted, provision is made for feeding both right and left fasteners-that is, fasteners that are to be applied on the righthand side of the shoe and also on the left-hand side of the shoe. Therefore the arrangement of apparatus is'duplicated on opposite sides of the machine. In the followingdescription, however, I will refer only to the construction and arrangement on one side of the machine, it being understood that in a double-acting or duplicated machine the parts hereinafter to be-described are the same on both sides.

I .will first describe the feed-hopper and its accessory parts and the means for operating the same, particular reference being had to Figs. 3, 4, and 5.

Suitably mounted or formed on frame is a plate E, having an upturned circularly-arranged flange. Suitably arranged to rest upon this upturued flange is a cylindrical casing F, forming what I shall term a hopper,7 into which the fasteners are dumped promiscuously, it being understood, of course, that only right fasteners are dumped into the hopper on one side of the machine and only'left fasteners are dumped into the hopper on the other sideof the machine. Preferably the hop-v per F and its supporting flanged plate E are arranged upon an incline, as clearly shown in Figs. l and 2, whereby the fasteners dumped in to the hopper gravitate to the lower portion of the hopper. If desired, the top of the hopper may be covered by a cap or plate G, a portion H of which may be hinged to provide ready access to the hopper, through which the fasteners may be introduced thereto.

Wvhile a machine constructed in accordance with my invention is adapted for use in distributing,feeding,inserting, and setting many forms of fasteners or other articles, it is, as above set forth, particularly designed for use in feeding, inserting, and setting the form of fastener shown in the patent to Heinemann referred to. This form of fastener comprises a coiled body portion formed of. one or more complete coils or convolutions and a superposed partial coil or convolution, such body portion terminating in ends K, projecting at substantially right angles to the plane of the coils .of the body portion, as more particularly described in the patent referred to. It will be seen, however, that the plane containing the two ends K of the fastener does not intersect the plane of the body portion or coils of the fasten er diametrically, but the plane containing said projecting ends cuts the plane containing the coils of the body portion to one side of the geometric center thereof, thus leaving a portion J (see Fig. 6) of the body somewhat greater than a semicircle and a portion L somewhat less than a semicircle, and in the particular form of fastener shown in said patent the portion L of the body contains only one strand of the coil, while the portion J of the body includes the superposed partial coil, as well as a portion of the complete coil of such body. Vith this form and construction of fastener clearlyin mind I will now proceed to describe the specific construction of hopper and cooperating means accessory thereto, which are particularly adapted to the feeding and delivering of fasteners of the particular type referred to, it being understood, however, that my invention is not limited to the feeding and distributing of fasteners of this particular type or construction, as the principles of the invention may be equally well adapted for use in feeding and distributing fasteners of other constructions.

Referring to Figs. 3 and 4t, it will be seen that the cylindrical casing F, forming part of the hopper,is so supported upon the upturned circular flange of plate E as to leave a clear space M between the lower edge of said casing and the top surface of said plate. This space is just sufficient to receive the body portion or coils of the fastener when resting liatwise upon the upper surface of plate E, with the ends K thereof projecting upwardly therefrom. In other words, the distance between the lower edge of casing F and the top surface of plate E corresponds substantially to the axial thickness of the body portion of the fastener. In the lower edge of cylindrical casing F are suitably cut or otherwise formed a series of slots or passages N, each of which being of an area permitting the passage therethrough of onlyone leg or end K of a fastener, said slots or passages being of a depth measuring from the lower edge of casing F, corresponding to the length of the legs or ends K of the fastener, and said slots or passages are spaced a distance apart corresponding to the distance between the two legs or ends of the fastener. From this construction and arrangement it will be seen that when the body of a fastener rests flatwise upon the upper surface of plate E and one leg or end of the fastener engages or enters one of the series of slots or passages .N the other leg or end of the fastener will enter the next adjacent slot or passage N, thereby -permitting the fastener to pass from the hopper, the body thereof passing through the space M and the legs thereof passing either successively through the same slot N or else one leg pass- IOO IIO

ing through one slot N and the other leg passing through the next slot or passage N. Preferably the lower edge of the casing F is of a thickness corresponding to the diametrical dimension of a fastener, whereby only one fastener at a time may be held with both its v legs in the same slot N or with one ofits legsin one slot and the other in the next adjacent slot; but such fastener will be retained in this position without danger of being displaced therefrom by the other fasteners contained in the hopper until the particular slots or passages in which the fastener legs or-ends are received are brought into register with the receivin g m outh orpassage of the raceway, presently to bemore fully described. When this position is attained, the fastenerpasses from the hopper, thus making roomfor another fastener to enter. Preferably and in order to facilitate the ready an'd easy passage of the fasteners from the hopper the slots or passages N radiate from the center of the hopper and preferably increase in area from the inner surface of said casin g outwardly toward the outer surface thereof, as clearly indicated at O, Fig. 3. Byvthis construction a hopper is produced from which the fasteners may pass readily and easily and without danger of choking or forming an obstruction. The upturned circular flange of support E is provided with an opening or passage (indicated at P, Figs. 3 and 4) arranged at a point opposite thelowest part of the -hopper when held in its iuclined position,whereby when the slots or passages N are brought into register therewith the fasteners may readily pass through and from the hopper. A chute or raceway suitably constructed and slotted, as will presently be more specifically described, is arranged with the mouth thereof communicating or registering with the opening or passage P, as clearly shown in Figs. 3 and 4. Suitably supported upon plate E, adjacent to the lower edge of the hopper, is a chamber Q, in which is mounted a disk R, having a roughened or grooved upper surface. The disk R is arranged with its upper surface fiush or in the same plane with the upper surface of plate E and also of the bottom of the feed-chute or raceway and is arranged to project partially within the lower edge of the hopper and also partially within to form part ofthe feed-chute or raceway. By imparting movement to this disk R the passage of the fasteners from the hopper and the starting of the saine down the feed-chute or raceway are facilitated and rendered more certain and positive.

As above explained, the hopper is arranged upon an incline, whereby the fasteners eontained-therein may gravitate toward the lower part thereof, whereby the legs thereof-may enter the slots or passages N and the bodies thereof may enter the space M. In order to still further insure a lodgment of the fasteners in such slots or passages and open space, said hopper F may be made movable. This movement maybe either a rocking movement or a rotation. In the particular forin shown, to which, however, I do not desire to be limited, said hopper or casing F is rotated. Many specifically-different arrangements of mechanism for rotating the hopper may be devised, and while, therefore, I have shown and will now describe a specific construction and arrangement of mechanism for accomplishing this purpose I do not desire to be limited or restricted thereto.

Suitably jonrnaled in an arm or other suitable part of framework A is a shaft S, Fig. 4, upon which is mounted to revolve loosely a pulley T. This pulley may receive rotation through any suitable arrangement of gearing from the main drive-shaft-as, for instance, through a belt 16, arranged to pass around and to be driven bya pulley 17, mounted on a counter-shaft rotated from main shaftB by means of the intermeshing gears 1S 19. In the palticular arrangement shown belt 16 passes from pulley 17 over a guide-pulley 20,thenee in an open bight around the driving-pulley of the hopper on one side of the machine, thence around Va guide 21v and in a crossed bight around pulley T, and thence over a guide 22 to pulley 17. By this arrangement the hoppers on opposite sides of the machine are ro tated in opposite directions. In order that the operation of the hoppers may' be controlled, provision is made for throwing the hopper into or out of action at will, and to this end the arrangement is such that nor- IOO mally the hopper is out of action. This re- Y sult is secured by mounting pulley T upon shaft S to revolve loosely thereon, and a clutch or other suitable engaging arrangement is provided for coupling said pulley and shaft to rotatetogether. I have shown a specific form of clutch wherein a pin 24, having its projecting ends secured in a elutchsleeve 25, (see Figs. 4 and 5,) is arranged to pass trans- -versely -through an opening (indicated at 23) through shaft S. This opening or slot 23 is somewhat elongated in the direction of length of said shaft, whereby the clutch sleeve or collar 25 and the pin 24 carried thereby may have a range of play or movement lengthwise of said shaft. This clutch-sleeve 25 is pro# videdwith a series of seats or teeth forming shoulders 26. (See Fig. 5.) Suitablysecured to pulley T is a plate 27, arranged to engage a shoulder'or tooth 26 of the clutch-sleeve 25 when said sleeve isfmoved into proper position therefor, thereby locking pulleyT and shaft S to rotate together.A The engagement or disengagement of sleeve 25 with detent or plate 27 may be effected in many different ways. In the particular form shown,`to which, however, my invention is not limited, a rod 2S is arranged to extend longitudinally through the bore of shaft S, said shaft being hollow, and pin 24 of the clutch-collar 25 is arranged to pass transversely through an opening or passage in4 said rod 28. yA spring 29 is arranged to normally maintain rod 28 in position to hold clutch-sleeve 25 out of engagement with plate or detent 27. Rod 28 may be projectedcndwise against the action of spring 29 and in a direction to cause plate 27 to engage behind a shoulder or tooth 26 of the clutch-collar in any suitable manner, as by means of a handle or lever 30, pivotally secured to the framework and adapted to engage said rod.

Byproviding the 'clutch-collar 25 with a number of teeth or shoulders 26 it will be seen that by projecting rod 28 endwise to carry said collar into position for plate or detent 27 to engage a shoulder or tooth thereon such engagement is effected at once and Wit-hout material loss of time, as such clutch-collar is required to rotate in any event only through a short arc in order to bring the detent or plate 27 into alinement with the engaging surface of a tooth of the clutch-collar. Hopper F is secured to rotate with shaft S in any suitable manner-as, for instance, by means of a rod 3l, passing transversely through said shaft and connected at the ends thereof with said hopper. A

From the foregoing description it will be seen that the hopper is normally out of rotative or movable action; but by suitably manipulating lever 30 pulley 'l is clutched to effect a rotation of shaft S, thereby rotating the hopper.

Vhile l have shown and described a specilic construction of hopper whereby the-fasteners are enabled to pass therefrom, specific claim to such specific construction of hopper is not made herein, as the specific constructi on of the hopper is the joint invention of myself and E. D. Heinemann and forms th'e subject-matter of specific claims in the companion application above referred to. However, the specific construction and arrangement of means for rotating said hopper which I have just described are of my sole invention and will be specifically claimed herein@ I have indicated in the foregoing description that disk R, which is arranged to form a portion of the bottom of the chute or race- Way and also flush With the top surface of plate E and arranged to project slightly Within the hopper at its lower point, is movable' in order to insure and facilitate the passage of the fasteners from the hopper into the chute or racevvay.l This movement may be either a rocking movementor (and preferably) a rotation, which may be secured in any suitable 1nanner--as, for instance, by means of a belt 32, passing around a pulley 33 on shaft 34, upon which said disk is mounted.- This belt passes around a. guide-pulley 35 and over a driving-pulley36 on main shaft D. By this construction it Will be seen that a continuous rotation is imparted to disk R, and since said disk forms a part of the bottom of the upper end of the chute or raceway and also projects slightly into the hopper, With itstop surface flush or contained in the same plane with the bottom of the hopper, and also forms the bottom of the passage P, it will be readily seen that the fasteners are insured a passage and delivery from the hopper to the raceway Whenever the slots or passages N containing the legs thereof are brought over said disk R and into register With passage P through the' upturned flangeof plate E. The arrow in Fig. 3 indicates the direction of rotation of disk R.

It sometimes happens that a fastener passes from the hopper with the Wrong leg thereof in advan ce-that is yto say, it is necessary to present the fasteners in absolutely uniform position to the action of the setting mechanism-and since the legs of a fastener are contained in a plane which intersects the body of the,fastener to one side of the diameter thereof it is necessary in order to secure the desired uniformity of feed and delivery of the fasteners that they be always delivered into the feed-chute or raceway so that the plane containing the legs of each fastener will be on the same side of the parallel plane containing the diameter ofthe body of said fastener. Therefore it is necessary to provide means whereby in the event a fastener passes from the hopper with the wrong legin ad- Vance-.that is, with the plane containing the legs of the fastener on the left-hand side, as viewed in Fig. 6, of the parallel plane containing the diameter of the body of the fastenerit may beturned around side for side,

`so that it may pass down the chute or race-4 Way uniformly. To accomplish this result,

the slot or opening at the upper end of the chute or raceway is provided with a projecting lip 38 (see Fig. 3) in one Wall thereof and a corresponding or coperating projection 38 in the opposite wall thereof, the two projections 38 38' forming a contraction in the area of the opening of such slot' to a point just enabling a leg of a fastener to pass singly therebetween. Immediately below the projecting lip 38 is a notch or recess 37 in the wall of such slot,which'notch or recess, together with IOO IIO

a corresponding and cooperating depression 37 in the opposed Wall or edge of the slot, forms an enlargement in the slot in the feedchute or raceway of an area adapting a fastener to be turned axially therein. The disk R forms a movable bottom for the feed-chute at these points. The operation ris as follows: In case a fastener is delivered into the upper end of the raceway with the proper leg foremost the fastener will be swept or carried down the raceway by the accelerating feed-disk R until the narrow channel between projecting lips 38 38' is-reached. These projecting lips are so relatively arranged with respect to the underlying chamber of the raceway, which receives the body of the fastener, that if the fastener is in its proper position the legs thereof will readily and successively pass through such contracted channel between said lips and will pass on in this sameposition through the enlargement in said passage formed by the notches or depressions 37 37 and deliver into. chamber 39 of the feed-chute or raceway,

' a sloth) of'which is in ennemi-.nt with the contracted opening between lips ,38 38', and through which slot 40fthe legs of the. fastener project. If, however, the wrong legof a fastener is foremost when the fastener reaches the contracted portion of slot 40 between lips 38 38', it will slightly tilt jto permit the foremost leg to pass through such contracted pas,-

sage, and the lip 38 will form a detent for thev rear leg thereof, whereupon gravity orthe movement of plate R will cause the foremost leg after it passes'through the contracted opening to tilt orswing in the'opposite direction around said lip and into the seat orv depression 37',v thereby permitting the rear or hindmost leg to pass through the contracted passage and to swing around into position to be the foremost or leading leg, thereby enabling the fastener to proceed properly and in theproper manner downthe chute or raceway. It will beseen that since the fastener passes from the hopper directlyinto the feedchute, if started in the proper manner in the -rst instance,the particular arrangement just described operatesonly when the fastener passes from the hopper inan improper position.

The feed-chute or raceway is most clearly having a slot 40, through which the legs of In order to accommo the fastener project. date the particular form of fastener shown,

Ythe slot 40 is arranged vsomewhat to one side of the central line of chamber 39, so that the larger portion .l of the body of the fastener lies on one side and the smaller portion L on the other side. In other words, and as clearly indicated in dotted lines in Fig. 3, that portion of chamber 39 which receives the portion J of the fastener and which lies on one side of slot 40 is of greater area than the other side of the chamber 39 which receives the portion L of the body of the fastener. Therefore unless-the fastener is delivered in a proper manner to the raceway it cannot enter or be fed down the chute or raceway. It will also be seen that the fastener is delivered from the hopper with the ends K thereof projecting upwardly. In order that these ends may beinverted when presented to the action of the setting-dies, the raceway (indicated generally at W) is reversely bent or curved upon itself, as clearly shown in Fig. l; but speciti claim theretois not made herein, as the subject-matter thereof is covered speeicallyin the claims of the joint application above referred to.

From the foregoing description it will be seen that the fasteners are delivered into the raceway in single column. However, it sometimes occurs that the fasteners are delivered to the raceway more rapidlythan they are de'- livered from the lower or delivery end of the raccway. In such event the raceway becomes filled with fasteners and a choke is liable to occur. In order to prevent and avoid this objection, it is desirable to provide means for automatically arresting the' feeding of the fasteners when the raceway becomes filled.

. Many specifically different arrangements may be 4devised for accomplishing this purpose and still fall withinA the spirit and scope of my invention.. Ido not desire, therefore, to be limited or restricted to the exact details of construction andv arrangement now to be described. In the form shown, particular reference being had to Figs. 1, 2, 14, l5, and 16,-.a

Wheel 41,havingprojecting pins42,is mounted to rotate in such relative position and relation as to permit the pins 42 to project through an opening in raceway W and into chamber 39 of said raceway, so that said pins engage the column of fasteners in case the vraceway becomes filled, whereby rotation of said wheel 4l is arrested. Upon shaft 43, carrying said wheel, is mounted a peculiarly-shaped spiral gear 44, having grooves cut in the periphery thereof and extending somewhat spirally with respect to the axis of vrotation of said gear. Arranged to mesh with this gear 44 is a 'worm 45, mounted on a longitudinallymovable shaft 46, suitably journaled in a fixed sleeve 47'r to rotate therein, but capable of longitudinal movement therethrough. A pulley 48 is suitably coupled to rotate with shaft 46, but permitting said shaft to move longitudinally through said pulley. This is accomplished by means of a pin 48', having its ends secured to a flange formed with pulley 48 and arranged to project transversely through a slot 47' in shaft 46, said slot being elongated in thedirection of length of said shaft. From this construction it will be seen that shaft 46 is always coupled to pulley 48 and rotates I oo to be moved endwise relative to said pul' ley. Upon shaft or rod 46 is mounted a collar 49, and a spring 50 is interposed between said collar and the end of sleeve or casing 47, the normal action of said spring being to maintain shaft 46 in one limit of its longitudinal movement. Pivotally mounted lupon a fixed part of the framework is alever 52, (see Fig. 1,) lthrough the upper end of which shaft 46 is arranged to project, the collar 49 being arranged on one side of said 1ever 52 and a head 5l on the end of lshaft 46 being on the other side of said lever. The

vlower end `of said lever is formed into a hook 53, forming a retaining-guide for lever 30. Formed n lever 52 is a hook or shoulder 54, operating as a retainer for lever 30 when said lever is rocked into position to establish engagement between driving-pulley T and hopper F, a slight spring 55 serving to hold said shoulder 54 in position to engage lever 30. Continuous'rotation is imparted to shaft 46 by means of a belt 56, driven from pulley 33 and passing over pulley 48. The operation of this part of the apparatus is as follows: Rotation is imparted to the main drive-shaft. The attendant then rocks `lever 30 into posi- IIO `engages the top of the column thereof, the p rotation of said wheel, and hence also of its supportingshaft and spiral gear 44, 'is arrest-ed. .Thereupon said gear 44 operates as a stationary screw-block with respect to worin l 45, which is continuously rotating, and hence said worm 45, and also shaft 4G, isdrawn longitudinally until the teeth or slots which form the engagement between gear 44 and worm 45 are cleared by worm 45, as indicated in Fig. 15. This longitudinal movement of shaft 46 is against the action of spring 50, the action of which normally tends to'return worm 45 into rotative engagementwiththe gear-v slots of gear 44. The longitudinal movement of shaft 46, as above mentioned,'causes the head 5l on the end thereof to engage lever52 and rock the same against the action of its spring 55, and `in a direction to carry shoulder 54, formed thereon, clear or out of engaging position with reference to lever 30, thereby releasing said lever and permitting the same to drop. Thereupon spring 29 will cause rod 28 to be returned to its normal position, such movement being endwise and in a direction to cause clutch-sleeve 25 to become disengaged from plate or tooth 27, thereby arresting the rotation of the feed-hopper, and hence arresting the further feed of the fasteners. This relation of the p arts is maintained until pin-wheel 4l is again permitted to rotate-that is, until the fasteners are de# livered in sufficient numbers f rom the lower end of the racewayl to cause the top of the column to descend sufficiently for the ends of the pins 42 to be cleared, thereby releasing said pin-wheel and permitting the same to rotate freely. Thereupon spring 50 operates to return shaft 46 to its initial position, with worm 45 intermeshing with gear 44, as shown in Fig. 14. This movement, however, docs not result in starting up the hopper, and therefore a feeding of the fasteners from the hopper will not be resumed. Such resumption can only be accomplished by the attendant again rocking lever 30, thereby causing pulley T to be clutched to shaft S, and when said lever 30 is rocked into position to be retained by shoulder 54 the delivery of the fasteners from the hopper is resumed. Moreover, the tendency of spring 50 to return shaft 4G to the position thereof indicated inFig. 14

is opposed by shoulder 49 bearing against the,

side of lever 52, and it is only when lever 8O is raised into position to be en gaged by shoulder 54 that the force of said spring is exerted to accomplish the endwise movement of shaft 46, as described.V

I will now describe a.specic construction andv arrangement of fastener delivering, setting, and clenching mechanism, to which, however, Ido not desire to be limited. In the form shown,Vdesignates a casing in which the plungers are arranged to operate. As

vshown in Fig. 7 and in detail in Fig. 9, `the plunger is formed in two separate parts 57 5,8, the part 5S forming the setting-plunger proper and the part 157forming the operating part of the plunger. f Each of these parts `.of the plunger is bifurcated or forked in the eind thereof, the bifurcation or fork being formed by removinga longitudinal segment from diametrically oppositesides thereof, as clearly shown in Figs. 8 and' 9. The fork of one portion of the Lplunger is arranged to normallystraddle and work in the fork of the other section ofthe plunger. The section 57 of the plunger is connected to a plunger-head 50, suitably reciprocated from a crank-pin 60 on a'disk 6l, mounted on `and rotating with main shaft B through a connecting-link 62. (See Fig. l.) Thus continuous reciprocation is imparted to the portion 57 of the plunger. The normal position of the upper end of part 58 of the plunger is such that the reciprocating part 57 works freely thereon; butat the upper limit ofeach reciprocation the lower end of said upper part 57 clears the upper endof the lower part 58. An arm 63 is connected to the lower part 58 of the plunger, said arm projecting through a slot or opening 64 in casing V. To said arm is pivotally.

connected the free end of a rod G5, said rod being pivotally connected at its other end to a crank-arm 66, looscl y sleeved upon a short shaft, (indicated in dotted lines at G6', Fig. 13.) Rigidly mounted upon to rock with said shaft 66 isa second crank-arm 65', to the end of which is yieldingly connected a rod67 through spring 68. By suitably projecting rod 67 end wise, as by .means of a foottreadle, (not shown,) shaft 66/ is rocked, and by suitably clutching crank-arm 6G to rock with said shaft bar is drawn endwise, thus rotating the lower section 5S of the plunger. Of course this rotation of said lower part of the plunger is not permitted, although an endwise tension is imposed on rod 67 until the lower endof the upper section 57 ofthe plunger is freed from engagement with the upper end of the lower portion 58 of said plunger. Therefore itis not necessary that rod 67 be projected endwise only when such disengagementtakes place, for it is obvious that an endwise tension imposed upon rod 67 by the operator will be taken up in spring GS; but such tension will not be operative to effect a rocking of portion 5S of the plunger until it is disengaged from -portion 57; but the moment such disengagement takes place a partial axial rotation of portion 58 of the plunger is accomplished.

A spring 69, connected IOO IIO

ger.

at one end to the frame and at the other end topcrank 67, serves to normallymaintain portion 5S of the plunger in position for the portion 57 to straddle and reciprocate telescop-` ically thereon. Vhen, however, the lower section 58 of the plunger is partiallyrotated, as above explained, the ends of the solid segments of the bifurcation or fork of section 57 of the plunger 'are brought into -alinement with thel ends of the solid portions or segrments of the fork of section 5S of the plun- Thereafter the downward reciprocation ofthe portion 57vof the plunger pushesv the portion-58 of the plunger downwardlybefore it. The groove G4 in the casing and through which arm 63 projects is'so shaped, as shown in Fig. 13, as to vpermit the down-ward movement of the portion 58, but preventsrelative rotation of said portionv d'uring such downward movement after lit has once been. ro-

.tated'into position to cause file abutmeut above referred to. In other words, said' slot 64 is similar to a bayonet-joint, one end thereof being turned or bent away from the main portion to permit the axial rotation of the portion 5S, but preventing endwise movement thereof, the other portion of the slot permitting endwise movement of said section of the plunger, but preventing rotation thereof. A spring 70, connected at one end to bar 65, serves to normally elevate or return plun ger 5S to its upper limit, and said spring 70, in conjunction with spring 60, serves to return said portion 5S to its initial or normal position to be straddled by the forks or bifurcations in the end of the Lipper section 57 of the plunger, thereby permitting said upper section of the plunger to slide freely thereon.

The downward movement of the plunger above described serves to insert a fastener, which has previously been placed in position in line therewith, in the material to which the fastener is to be applied and, in conjunction with the anvil or die, to clench the ends of the fastener on the under side'of such article. I have described the crank-arm 66 as loosely sleeved upon shaft 66', but may be clutched to rock therewith. This clutching may be etfectedinmanydiierentways. Ihaveshown a simple arrangement for'accomplishing this purpose, to which, however, I do not desire to be limited, and wherein said crank-arm 66 is provided with a perforation in the sleeve thereof, into which a pin (indicated in dotted lines at may be arranged to project, said pin beingcarried b v a piece 69', connected to rotate with shaft 6G', but yieldingly mounted, so as to be moved in a direction to disengage pin 70vl from engagement with the sleeve or hub of crank-arm G6. In van apparatus cmbodyingthe duplicated arrangement, asv

above described, on opposite sides of themachine this arran gement of coupling the crankarms 66 or uncoupling the same is desirable and important, for the reason that thereby the plunger on either side of the machine may be readily and easily thrown out of action 7, s, 1o, luana 13, refthe joint application erence-sign 72 designates a bar or rod mounted to slide ina seat formed in head V. A spring 73, arranged to rest at one end upon a pin 71,

Vfixed in head V, bears at the other cndagainst the upper end or wall of a slot 7l', formed in saidl rod or bar 72 and normallybut yield-- ingly maintains said bar in elevated position.

Upon the lower end of said bar are pivotally mounted plates 74 75, each provided .with a wing orlprojection 76 and also with an angularly-projecting plate 77. The plates 74 75 are held slightly separated from each other by means of a projection 7Son the lower end of arm 72, said projection entering the space between the angularly-projecting portions or plates 77, as shown in Fig. Il. 7 9 normallyoperates to press the angular projections 77 toward each other. The space between the angular projections 7.7 is just sufficient to receive therein the legs of a fastener, the body portion of the fastener resting upon the upper surface of said plates or projections. These angular plates or projections 77 are arranged in position to support a fastener in alinement with the plunger 5S, the projection 78 also serving as a stop, against which the coil of the body portion of the fastener rests. Vhen the plunger is operated endwise, as above explained, therlower end thereof tirst engages the uppersurface of the body of the fastener. The continued projection or endwise movement of section 5S ofthe plunger carries downwardly with it the arm or bar 72 against the action of spring 73. In the path of downward movement of plates 74 75 are arranged fixed arms or fingers 8O in position to engage the projecting wings 76 of said plates 74 75, thereby rocking said plates about their pivots against the action of spring 79, thus causing the angular'projections 77 to separate, and hence releasing the fastener and permitting it to pass between such anglilar project-ions. The parts are so relatively arranged, however, that this separation does not occur until the ends of the fastener have been inserted in the material sufficiently to obtain a firm hold thereon.

It is import-ant ythat upon each downward reciprocation or movement of the plunger 58 a fastener be certainly and positively deposited or delivered upon the supporting angular projections 77 in order that the machine may not miss setting a fastener upon each downward action of plunger-section 5S. 'In order to accomplish this result, I have shown and,

will now describe a specific construction and ICO [lo p I arrangement; but I do not desire to be limited vIO a bar S2,the sliding movement thereof being' suitably resisted, as, for instance, by means of a springSS, the tension of which maybe regulated by set-nut Si. Rod 82 is pivotally connected at its lower end to the angle of an anglelever 85, which is provided at its free end with afoot 86, serrated orroughened on its under surface and arran ged to project through a slot or opening in rac'eway W in position to engage the top surface of the fasteners.' In a fixed bracket 87 is journaled a rock-shaft 88, upon Qne end of which is mounted an arm S9, loosely pivoted to one of the arms of cranklever 85, as by means of a slot-and-pin connection,`(indicated at90, Fig. 7.) Upon the other end of rock shaft or pin 8S is mounted an arm 91, arranged to, project into the path of movement a convenient reciprocating or movable part of the apparatus which moves with the plunger-section S-such, for instance, as arm G5. (See Figs. 7 and S.) The rocking of rock-shaft or pin 8S, is opposed by means of a spring 92. The operation of this part of the apparatus is as follows: Upon each downward reciprocation. of portion`58 of the plunger arm 65 engages arm 91 and rocks the same, and with it rock-shaft 88 and arm 89, in the direction indicated by the arrow, Fig. '7,

and against the action of spring 92. This move-l ment of arm 89 through its pivotal and loose connection with the angle-arm irst rocks the said angle-arm about its pivotal connection with bar 82, which rocking movement is continued until tlug or heel projection' 93, formed on said angle-arm, engages said bar 82 as a stop. This rocking movementof angle-arm S5 raises foot S6 out of engagement with the fastener. 93 has engaged bar 82, whereby angle-arm 85 can no longer rock about its pivotal connection with bar 82, the continued rocking movement of bar 89 projects bar S2 endwise into casing 81, carrying with it angle-arm S5, with the foot 86 thereof still elevated. This operation takes place during the action of the plunger-section 58 in effecting an insertion of the fastener previously deposited upon the retaining plates or lian ges 77. When plunger 58 is again elevated or returned to its upper limit of movement, bar 65 releases arm 91, whereupon spring 92 returns shaft 88 and arm 89 to their normal and initial positions. The first result of such return movement is to cause angle-arm 85 to rock-about its pivotal connection with bar 82 and into position for the foot S6 thereof toengage upon the top surface of the next fastener. Thereafter the causes bar 82 to be withdrawn endwise from After a lug or projectionv 'casing S1, carrying inadvance thereof the angle-arm S5, thereby positively pushing the fastener engaged by the under roughened surface of footrSG and delivering t-he same positively'from the lower end of the raceway and upon the retaining plates or flanges 77 and into position in alinement with plunger 58.- The foot 86 serves thereafter to hold the fastener in this position and against the projection 78, as above,explained, as apstop until the plunger ragain begins its descent, andV thereupon the foot S6. is first raised out of engagement with the fastenerand then withdrawn,"as above explained, and without disturbing the position occupied by the fastener.

In line withv the plunger-section 58 and arranged to cooperate therewith is a setting-die or anvil 94(see Fig. 12,) suitablyand adjustably mounted in a l'fixed' block 95, forming part of the framework.r4 The die or anvil 94 may be vertically adjusted by means of lscrew 97 and'held in adjusted position by set-screw 96. A plate 98, having a central opening, as at 99, through whichl the top surface of die or anvil 94.- is arranged to pass, is supported on 'the bed plate or block 95 and isprovided with upturned flanges 100, arranged, preferably, in right-angular relation with respect to each other, thereby forming retaining lianges or guides for the article to which the fasteners are to be applied. thisl construction it will be seen that uniformity in attaching fasteners to articles is securedthat is, the article is held thereby in uniform relation to the setting-plun ger when in position to receive a fastener.
